Specification of Letters Patent.

Patented Aug. at, rare.

Application filed December 6, 1916. Serial No. 135,481.

of Ontario, in the Dominion of Canada,

plumber, have invented new and useful Improvements in Can-Openers, anddo hereby declare that the following is a full, clear, and exactdescription of the same.

Our invention relates to improvements in can-openers, in which thecan-opener has two levers, the one being straight is provided with apiercing point at its extremity, and the opposite lever has a curvedjaw, at the extreme end of which is located a circular knife, with aguide directly over said knife. The levers are operated on a pivot.

The invention is illustrated in the accompanying drawing, in whichFigure (l) is a top view of the can-opener, showing how the differentparts are shaped, and where they are Located.

Fig. (2) is a side view of the can-opener, showing where the circularknife is located, also to show how the cork-screw is made to form thepivot for the levers.

Fig. (3) is an end view showing the guide which rides around on the topof the can to keep the circular knife in its proper course, also showinghow the cork-screw is held in position when not in use.

Similar figures refer. to similar parts throughout the several views.

4 and 5 represent two levers, one straight and one curved, pivoted at10. The straight lever 4; carries a piercing point 8' offset from one ofits ends secured thereto by'a riveted head 11. The curved lever 5 has anextremity bent over upon itself and 1 represents a knife journaled insaid bent over portion by means of a rivet 9 and 2 indicates a guidecarried b said rivet. The pivot 10 is extended and ormed into acorkscrew 6. The curved lever 5 is providedwith a bottle opener 3 and aconcaved portion 7. 13 represents the top of a can to be opened.

The piercing point (8) is inserted into the center of the can, andpressed downward until the levers (4) and (5) are in a horizontalposition, placing guide (2) on top of the outer edge of said can, withthe cutting edge of knife (1) pressing'against the outer upright surfaceat a distance of about fath of an inch from its top, and forced throughthe tin by the levers (4) and (5) being drawn together and movedhorizontally in a circle, making a vent in said surface until the top ofthe can is severed from the body of said can.

Bottle cap remover (3) is used to remove metallic caps from the tops ofbottles by placing the point underneath the edge of said caps and pryingupward.

Cork-screw (6) is used for taking corks from bottles by inserting saidcork-screw into the cork to be drawn, by a righthand circular motionuntil said corkscrew has sufficient hold and is to be drawn upward. The'end of cork-screw (6) also forms the pivot at (10) for levers (4) and(5).

We are aware that prior to our invention can-openers have been made withcircular knives and piercing points. We therefore do notclaim such acombination broadly; but

What we do claim as our invention and desire to secure by LettersPatent, is-- A can-opener comprising a pair of levers pivoted togetherintermediate of the length, one of said levers having a straight end,the other of said levers having a curved end, the end of the leverhaving a curved end being formed with a U-shaped extension, a pivot pinextending transversely across the U-shaped extension, a rotary cuttingknife mounted on the pivot pin, a guide on the top of the U-shapedextension adapted to engage the edge of the can and a piercing point onthe extremity of the lever having a straight end, substantially 'as andfor the purpose specified.
